What Is The Cost Of Water Heaters?

Electric water heaters cost less to buy than gas heaters initially, although they cost more in the long run. Do not consider the upfront cost to add up the installation fee too while making the purchase.

Since water heaters are expensive, go for models that are energy efficient and energy star rated.

Energy-efficient heaters may cost more in the beginning but will be budget-friendly over the years.
